STOCKHOLM — The list of troubles linked to Justin Bieber’s tour of Europe grew again after Swedish police said Thursday they had found drugs and a stun gun on the pop singer’s bus.

No arrests were made since the bus was empty at the time, Stockholm police spokesman Lars Bystrom told The Associated Press.

Police said they decided to act after smelling marijuana coming from inside the bus while it was parked outside the hotel where Bieber, 19, was staying in the capital. Drug officers searched the bus during the concert while Bieber was on stage, Bystrom said. He said a small amount of drugs and a stun gun were discovered during a search of the bus, which had been parked under the Globen concert venue in Stockholm, where Bieber was performing Wednesday. Bystrom declined to identify the drug, saying that it was sent to a lab for analysis.

Bieber, who arrived in Helsinki, Finland, later Thursday to perform in a concert the following evening, tweeted after his arrival: “some of the rumors about me .... where do people even get this stuff. Whatever ... back to the music.”

The incident is the latest in Bieber’s tumultuous European tour, which has included a monkey detention, a Holocaust museum furor and a health scare.

In Britain, the singer struggled with his breathing and fainted backstage at a London show. He was taken to a hospital, only to be caught on camera clashing with paparazzi.

The Canadian teenage idol had to leave his monkey in quarantine in Germany since he didn’t have the necessary papers for the animal.

Bieber then became the focus of intense criticism in the Netherlands for writing an entry into a guestbook at the Anne Frank House museum in Amsterdam, saying he hoped the Jewish teenager, who died in a Nazi concentration camp, “would have been a Belieber” — or fan of his — if her fate had turned out differently. The comment provoked a flood of comments on the museum’s Facebook page, with many people criticizing the singer for gross insensitivity.

Anne Frank hid with her family in a small apartment above a warehouse during the Nazi occupation of the Netherlands during World War II. Her family was caught and deported, and Anne died of typhus in Bergen-Belsen in 1945. She was 13 years old when she began keeping her diary in 1942. Like many teenage girls, she made a collage of the celebrities of her day — movie stars, dancers, and royalty — and kept it on her bedroom wall.

In Norway, where Bieber enjoys enormous popularity, education officials in a remote district rescheduled midterm exams for high school students so that the singer’s fans could attend the concert in the capital and not have to worry about missing the tests.

LOS ANGELES — Jane Fonda is planning to shed a few tears on Saturday.

That’s when the Oscar winner will place her hand and footprints next to her father’s in the concrete shrine to celebrity outside Hollywood’s Chinese Theatre. Then she’ll present a special screening of the film she made with her dad, 1981’s “On Golden Pond.” The cement and cinematic tribute is part of the 2013 TCM Classic Film Festival, which is honoring Jane Fonda.

“I am very, very excited,” Fonda, 75, said in an interview this week. “I thought probably I would die and this would never happen. I’m just really thrilled that it actually is happening and not only that, but I get to put my hand and footprints right next to my father. ... I’m just so happy I’ll probably cry.”

The honor inspired Fonda to reflect on her career, which hasn’t slowed since she returned to acting in 2005 after a 15-year hiatus.

“I’ve made some really good films. There’s also a lot of films I wish I could do over again,” she said. “But I’ve been lucky: I’ve worked with some great directors, and I feel like I’m still a work in progress as an actor. I feel like I’m still learning.”

After her guest-starring stint on “The Newsroom,” she’s more interested than ever in television.

“I’d love to have a television series of my own,” Fonda said. “I’m hoping that might happen.”

A fitness pioneer, Fonda continues to focus on health and wellness with a series of videos aimed at older exercisers. She inspired countless Oscar watchers earlier this year with her fitted, bright yellow gown, and she serves as L’Oreal’s oldest spokeswoman.

“When you’re younger, you don’t have to put so much time into it, but also I didn’t care that much. I was an activist and I didn’t think so much about how I appeared,” she said. “As I’ve gotten older, I’ve paid more attention to how I dress, how I look, what makeup I use, what skincare products I use... I guess one reason that I put more effort into looking good now is because I think it gives hope to other women. It takes the edge off the fear that young people have of getting older.”

The wisdom and openness that come with aging are easy to wear well, and Fonda said she’s happier now than ever.

“This event that’s coming up where I get to put my hand and shoeprints next to my dad in front of the Chinese Theatre, it’s coming at a very happy time in my life,” Fonda said, “and making it even happier.”
